Our expectation, working with our partners at Imperial Oil, is that they will start construction of a major pilot plant next year for the non-aqueous extraction technology. It will take about a three-year cycle to build that, prove the technology, and see whether it's ready for large-scale commercialization. If it is, then it would take another three to four years to go through construction and commissioning. So for a major industrial technology, you're looking at somewhere between six and eight years to go from lab conception through to full operation. Our new catalysts are a little further away. They're a great curiosity on the lab bench. We're probably looking at five to eight years before we really know the potential there; it's longer term.
